Her şeyden önce, hatalarının PDO::setAttribute
method, to set the PDO::ATTR_ERRMODE
(error reporting) seçeneğini kullanarak, PDO tarafından ele nasıl ayarlayabilirsiniz.
Özellikle, bu yüzden bir hata olduğu zaman bunun yerine bir "hata" raporlama, istisnalar atar -- that's what I generally do. PDO'yu yapılandırmak mümkündür
Then, when a method can throw an exception, it should be indicated in it's documentation -- generaly, it's in the "Return value" section.
Örneğin, PDO::prepare
can throw an exception -- depending on error reporting (see what I wrote just before),
If the database server cannot
successfully prepare the statement,
PDO::prepare()
returns FALSE
or
emits PDOException
(depending on
error handling).
As a sidenote : if you find a function / method that throws an exception, and it's not indicated in its documentation, it might be a good idea to create a bug report (see http://bugs.php.net/ ), so that problem is corrected ;-)
(Errors / mistakes / missing informations in the documentation are treated via the bug-tracker, like any other bug)
